BACKGROUND

1. Technical Field

The present disclosure relates to a stand assembly and an electronicapparatus.

2. Description of Related Art

Computers are the most common and convenient tools in modern life thatfacilitate daily life and work. Because of the following limitationsincluding having a wide variety of peripheral devices, being difficultto install, and only being utilized at fixed points, a typical desktopcomputer is not portable. A tablet personal computer has an advantageover the desktop computer because it is portable and convenient to use.

However, the tablet personal computer only has a touch screen thatcauses inconveniences and problems to users when being operated orapplied. For example, the touch panel of a tablet personal computer canonly be placed horizontally and is not allowed to be placed laterally orleanly. Hence, users need to bow their heads to watch the screen thatcauses neck and shoulder discomfort. Even if the tablet personalcomputer leans on another object, inconvenience during operation stillexists because the tablet personal computer is not easily to be fixedand tend to slide. With the massive production of tablet personalcomputers, stands for the tablet personal computers have already been onthe market. Or, a tablet personal computer with a stand on the back ofits body has been designed to facilitate standing the overall unit on atable and moving the overall unit to the front of users.

However, most of the prior art stands are in the form of supportbracket. The expanded prior art stand and the body of the tabletpersonal computer form a V-shaped structure, and the prior art stand maymove telescopically. Its mechanical operation is not novel at all. Inaddition, a spring is utilized as a fixed point around which torque isgenerated in most of the prior art stand designs. The spring may becomeelastically fatigued after prolonged use. Moreover, molds for parts inthe prior art stand cannot be shared with different parts to make thecost high. The large overall size also results in a waste of packagespace.

In order to solve the aforementioned problems, the industry is eager toinvest R&D resources so as to provide a stand assembly with novel designconcept for the stand.
